    Abstract: A rotary magnetic motor having a rotor configured to magnetically interact with a stator to obtain rotation of the rotor about its axis. The stator has a magnetic structure of a generally involute shape around the axis of rotation. The stator magnetic structure has a plurality of permanent magnets defining a first magnetic face of a first polarity. The rotor has a magnetic structure of a generally circular shape around the axis and inside the stator magnetic structure. The rotor has a plurality of permanent magnets defining a second magnetic face of a second polarity. The magnetic attraction and repulsing of the aligned magnetic faces with a progressively narrowing radial gap, resulting from the involute shape, rotate the rotor inside the stator. A magnetic pulse mechanism discharges a magnetic pulse of the first polarity to provide an additional pull to continue the rotation of the rotor through its full cycle.

  • Publication number: 20130147298
    Abstract: A method and apparatus for energy generation and conservation uses magnets to repetitively provide rotational mechanical energy. An actuator arm and coupled magnet is inserted into a rotating plane defined by other magnets which are positioned to do work based on the electro-magnetic relationships among the magnets. In one aspect, the magnets are actually comprised of a plurality of magnets so as to create a specific magnetic field. In another aspect, an actuator magnet moves in relation to a drive magnet and follows a path as perpendicular as possible to the magnetic field of the drive magnets. Consequently, a minimal energy path is taken through the magnetic field and a relatively small amount of input energy is required to operate the device. Using minimal energy to create potential energy also enhances the apparatus by minimizing the extinction of motion therein due to friction while powering other mechanisms.

    Abstract: A system accepts outside kinetic energy in various forms such as wind, rain or waterfall and produces electricity by use of traditional coils and magnets or other means. During lulls in obtaining outside kinetic energy, a wind wheel, water wheel or arm system will slow down and eventually stop. A system of magnets installed upon an arm system and upon a surrounding stationary housing 800 assists in rotating an arm system such that the arm system will require additional time to stop after a lull in outside kinetic energy. The artful placement and orientation of stationary housing magnets 250 in relation to moving arm magnets 200 assists in rotating an arm system powered by outside kinetic forces. The angles of the stationary housing magnets urge the arm magnets to move in the desired direction 900 of rotation. The system increases mechanical efficiency.

  • Publication number: 20120235528
    Abstract: The Toroidal Inductance Generator is a machine that creates electrical energy by orbiting three fields of multiple magnets inside and around, a copper wire toroidal coil. The toroidal generator is comprised of a copper wire wound toroidal coil, with a vessel core, containing a plurality of free moving rare earth magnets sealed inside the vessel core assembly. A magnetic shroud is affixed to the protruding shaft of an existing rotary means. This magnetic shroud and rotary means are concentrically positioned to rotate a plurality of magnets immediately adjacent to both the outside and the inside diameter of the toroidal coil. The vector fields of the shroud magnets overlap and interact with the vector fields of the magnets sealed inside the copper wire toroidal core. The internal magnets are caused to follow the rotating field from the applied external coercive magnetic force. The three combined orbits all contribute to the generation of electricity within the copper wire toroidal.

  • Patent number: 8258782
    Abstract: An angle detecting apparatus includes a rotor fixed to a rotating shaft, a pair of magnetic sensors arranged close to the outer periphery of the rotor so as to have a difference in angle (?/2) with respect to the center of rotation of the rotor, a differential operational circuit performing differential operation on detection signals output by the magnetic sensors to output a differential signal, and the angle calculating circuit calculating the angle of rotation of the rotating shaft based on the differential signal. The planar shape of the rotor is such that the sum of the distances between the center of rotation and the respective two points where two straight lines crossing at the center of rotation at a crossing angle of (?/2) cross the outer periphery of the rotor is constant, and the planar shape is symmetric with respect to a straight line passing through the center of rotation.

  • Publication number: 20120187786
    Abstract: The present disclosure relates to a magnetic motor including a drive magnet, a motion magnet, and an acceleration field. The drive magnet includes magnetic shielding, typically on a portion thereof, altering the magnetic field of the drive magnet. In some embodiments, the motion magnet has a cross-section that is generally in the shape of a ‘V’ or ‘A’. The acceleration field is created by the interaction between the drive magnet and the motion magnet as the motion magnet is passed through the altered magnetic field of the drive magnet. The altered magnetic field of the drive magnet may often be near a first end of the drive magnet. In further embodiments, the motion magnet can be operably coupled to an output shaft and rotate around the central axis of the output shaft. The present disclosure, also relates to a device, including the magnetic motor, for generating energy from a turbine.

  • Publication number: 20120153758
    Abstract: The Pulsating Permanent Magnet Powered Engine was designed and built as a new energy source by harnessing the strong magnet fields developed by magnets. Emphasis added when using Rare Earth Neodymium magnets. In this development the need to insulate, isolate and contain those magnet force fields became a challenge. This lead to the development of the bellcrank system. To gain horse power, the rating requires moving 550 pounds at a rate of 1 foot per second. The bellcrank system enables both the distance and the pound requirements to be met as qualifications for horse power. The principles of thermodynamics, stated as power in and power out do not apply here. Permanent magnets are charged with a very high electrical current, much like charging a battery but the battery power depletes with use, while the magnet does not, but both were charged to begin with.
